While i am not really an visualization specialist in any regard, i am still often dealing with the visualization of relatively complex multidimensional datasets. Among the usual and well known tools, matplotlib in combination with iPython, Gnu R and jupyter as interactive worksheet, i have found two very interesting projects: Glue and Parallel coordinates.

Glue is a system which allows the interactive exploration and investigation of complex and fragmented datasets, which is nicely demonstrated in a video:

As nearly the entire Drupal community which is using Drupal 7, i was also affected by the severe Drupal security bug. I have lost my website edits of the last weeks, therefore some blog entries and publications are missing right now.

The rollback of the installation here (and an entire server i do administrate elsewhere) was very annoying, but on the positive side i have to admit that i learned many new things.

For me (who is not that familiar with databases and SQL) it was a little effort to find the right SQL statement to retrieve the cleartext from a binary encoded mysql table from a mediawiki (1.18.1) installation. The following little SQL statement did the trick, it gives the user names of all users in cleartext:
